PILED FABRIC.

SPECIFICATION forming part of Letters Patent No. 423,781, dated March18, 1890.

Application led September 24, 1888. Serial No. 286,148. (No model.)

To all whom t may concern:

Be it known that I, CHARLES H. LANDEN- BERGER, a citizen of lthe UnitedStates, and a resident of Lawrence, Massachusetts, have invented certainImprovements in Pile Fabrics, of which the lfollowing is aspecification.

My invention consists of a fabric which can be rapidly and cheaplyproduced on a knittingmachine,and which constitutes anacceptablesubstitute for a Persian carpet or rug or like costly fabric nowproduced by tedious and expensive processes.

In the accompanying drawings, Figure l is a sectional diagram showingone method of making the fabric. Fig. 2 is a perspective diagram of theproduct of this method of manufacture. Figs. 3 and 4 are similardiagrams showing other methods of making the fabric, and Fig isasectional diagram of a piece of single fabric formed by severing theduplex fabric shown in Figs l and 2.

A A represent opposite backings; B, the

Y tufting or figuring threads carried back and forth between thebackings A, and D D binding-threads whereby the tufting-threads are tieddown or secured to the backings A A.

As shown in Fig. l, the backings A A are composed ofcoarse Woven fabric,and the tufting-threads B are drawn through these backings and form rowsof interlocked loops on the back of the same, eachthread B rst forming aloop on the back of one fabric A, and being then carried across andthrough the opposite fabric, forming a loop on the back of the same, andthen returning to the first fabric, in the manner clearly shown in thedrawings. There are two binding-threads D for each row oftufting-threads B, one binding-thread for each backing, and eachbinding-thread forms a rowr of stitches and serves to tie in the loopingor tufting thread to one of the backing fabrics.

Although the carrying of the tufting-threads through the backing fabricsand the interthrough the backing fabric and the interlooping of saidthreads on the backs of said fabrics should be resorted to.

A complete fabric need not necessarily be used for the oppositebackings, as single threads-such as shown in Fig. 4-may take the placeof such fabric, the tufting-threads being bound to said backing-threadsby bind- 6o ers D, as shown. These single threads are introducedsuccessively by means of a shuttle after the formation of each course ofstitches by the needles of the machine, as set forth in my applicationSerial No. 246,848, filed August 13, 1887. The use of the completefabric as a backing is, however, preferred, as it impartsgreaterstability to the product and facilitates the manufacture of the same.y j

In the diagram shown in Figi the tufting- 7o thread loops are notinterlocked with each other on the back of the fabric, but are simplybound down by the tying-threads D. In this case the loops lie closer tothe back of the fabric than when they are interlocked, and the same planmay be adopted when a complete fabric is used for the backing.

The fabrics shown in Figs. l to 4are double, and are intended to besevered centrally in order to produce two fabrics, each having a 8o -cutpile or tuft, as in Fig. 5, for instance, the

making of the fabric double in the iirs't instance being an importantfeature of my invention, as it materially facilitates and cheapens theprocess of manufacture.v

It has been heretofore proposed to make a single fabric havingbacking-threads such as shown in Fig. 4 and tufting-threads bound tosaid backin g-threads; but the objection to this plan has been itscomparative slowness, the 9o process requiring as long a' time to make asingle fabric as is required to make-a double one in accordance with myinvention.

In making figured goods two or more sets of tufting-warps maybeemployed,these Warps 95 y being under control of Jacquard mechanism, soas to follow the course demanded by the desired pattern to be produced.By this means any desired one Yof the set of Warp-threads controlled byeach guide may be used to form roo the crossing-thread from one fabricto the other, each of the threads not in use oating in proximity to thebacking fabric to which it Was last bound until lit is again called bythe jacquard to be bound into the opposite fabric.

Where a tufting-thread is used in making several successive stitches itWill pass directly across from one fabric to the other; but when suchthread is out of use for some time it Will, when next called upon, bedrawn across from fabric to fabric at a more or less acute angle, asshown in Fig. l,and when the threads'connecting the two backing fabricsare severed these diagonal threads will be longer than the straightthreads, the long ends being removed by any suitable shearing apparatus.Although the double fabric is not adapted for use in that form, it stillconstitutes a novel article of manufacture and sale, and may in manycases be sold rin that form by the manufacturer to another manufacturerprovided With proper facilities for severing the double fabric andshearing and finishing the cut-pile surfaces of the single fabrics thusproduced; hence I have presented claims for the double fabric.

It has not been deemed necessary to illustrate further than in Fig. lmechanism for producing the fabric, as this is fully described and shownin myapplication above referred to.

I claim as my inventionl. As anew article of manufacture, a fabricconsisting of opposite Webs or backings,

threads looped back and forth between the said opposite backings, andbinding-threads forming opposite rows ofstitcheswhereby saidcrossing-threads are tied down or secured to the opposite backings, asset forth.

2. As a new article of manufacture,` a cutpile fabric consisting of abacking A,co1n plete in itself and having a series of rows of pile tuftsor loops, anda series of rows of binding-stitches formed on the backingand engaging with said pile tufts or loops, sub stantially as specilied.

3. A cut-pile fabric consisting of a backing A,.complete in itself andhaving the series of tufts or loops, of the pile drawn through saidbacking and forming interlocked loops on the back of the same, as setforth.

4. A cut-pile fabric consisting of a backing A, complete in itself andhaving the series of tufts or loops `drawn through said backing, forminginterlocked loops on the back of the same, and tied'doWn or secured tosaidbacking by binding-threads, forming rows of stitches, as specified.

5. A fabric consisting of opposite webs or
